Harvard Health Publishing mentions six ways to improve and protect our vision:
1. Get regular eye exams — every two years before age 70 and yearly after that.
2. Control underlying conditions — chronic health problems such as diabetes and high blood pressure can hurt your vision.
3. Eat a healthy diet — foods rich in antioxidants may cut the risk of cataracts and age-related macular degeneration (AMD).
4. Stop smoking — Aside from genetics, smoking is the top risk factor for AMD and cataract progression.
5. Use eye drops — preservative-free artificial tears can make vision less blurry for those with dry eyes.
6. Use eye protection — when outdoors, wear sunglasses that filter ultraviolet (UV) rays, as prolonged exposure is associated with cataract formation and cancer on the eyelids. Additionally, wearing safety glasses at home or at work, when needed, can protect against injury.
